PHP with pdo-mysql in ubuntu 16.04

manpreet Best Answer 3 years ago

I've been trying to install php (7.2) in Ubuntu (16.04) with PDO enabled. I don't need php as apache module, because I want to use PHPs built-in server (in cli mode, like php -S localhost:80).

So, here is what i do:

sudo apt-get install php

sudo apt-get install php-mysql

sudo cp /usr/lib/php/7.2/php.ini-production.cli /etc/php/7.2/cli/php.ini

Now, in php.ini uncommented:

extension=pdo_mysql

And still when i run php -v I get the error:

PHP Warning:  PHP Startup: Unable to load dynamic library 'pdo_mysql' (tried: /usr/lib/php/20170718/pdo_mysql (/usr/lib/php/20170718/pdo_mysql: cannot open shared object file: No such file or directory), /usr/lib/php/20170718/pdo_mysql.so (/usr/lib/php/20170718/pdo_mysql.so: undefined symbol: pdo_parse_params)) in Unknown on line 0

php -m output:

openssl

pcre
Reflection

SPL
standard
zlib

I solved the problem this way:

sudo apt-get --purge remove php-common

sudo apt-get install php-common php-mysql php-cli

Now there is no error and php -m shows it has everything:

[PHP Modules]
calendar
Core
ctype
date
exif
fileinfo
filter

iconv

Still don't know what caused the issue in the first place
